Eligibility Criteria
Inclusion
- All eligible adult patients with compensated liver disease due to chronic infection with HCV and genotype 1 infection who are treatment naïve will be enrolled into the study.
- All racial and ethnic groups will be recruited into this study.
- Males and females: age \> 18 years
- Chronic hepatitis C: history of serum positive for HCV antibody (anti-HCV) and HCV RNA. Patients should have evidence of chronic hepatitis with a minimum fibrosis score of 1 on liver biopsy done within 6 months of enrollment.
- Insulin resistance based on HOMA index value (HOMA-IR) of \> 2.0 during screening. HOMA-IR is a well recognized and validated index of insulin resistance in both non-diabetic and diabetic populations and has been shown to have a good correlation with 'clamp' techniques that are intensive. HOMA is also used routinely to assess longitudinal changes including assessment of the effects of treatment. In general, a HOMA-IR value of \> 1.5 is considered abnormal based on repeat testing measurements performed by both HOMA assessment and by euglycemic clamp technique and is considered representative of decreased insulin sensitivity. Although insulin secretion is pulsatile, the correlation between HOMA computed from repeat sampling (using a mean of three samples taken at 5-minute intervals to compute HOMA) and the value obtained from a single basal sample to determine insulin sensitivity has been shown to be near perfect even in patients with type 2 diabetes (r = 0.99, p \< 0.0001). The investigators will use a HOMA-IR value of \> 2.0 as part of the inclusion criteria in this study.
